Chalkboard with description of periodic table notation for argon. There is a square with three values in it. Top has atomic number, center has element symbol, and bottom has atomic mass value. The atomic number equals number of protons and also the number of electrons in a neutral atom. Atomic mass equals the mass of the entire atom.
This is a image of Mendaleev Square. It shows how Argon is featured on the periodic table. This shows the atomic number and atomic mass of Argon. Also that Argon has 18 protons, about 22 neutrons and 18, electrons. Argon is also a gas at room temperature, meaning it is oderless,colorless, and tasteless.
